This method is using two times conformal transformation method and mirror theory to calculate the characteristic impedance. 这种方法是采用两次保角变换结合同轴线特性阻抗公式进行特性阻抗计算。
The mathematical derivation of the formulae used for calculation of the characteristic impedances of the coaxial branched strip lines are given. 本文给出同轴分支带线特性阻抗计算公式的数学推导。
